NIWA crew face record time at sea
And even though they’re back in their home port, the crew still can’t leave the ship until they return a negative COVID test so the beer will have to go on ice for a little while longer.Unfortunately, it hasn’t been plain sailing for the ship with Mr Brosnan estimating they had “about one and a half days of good weather” the entire time they were away.
“We were hit by storm after storm. The ship was rolling and rolling all the time.”
Asked how they managed to keep their spirits up for so long without getting off the ship, Mr Brosnan said it was a matter to taking things one day at a time.
There were two stops in Fremantle for refuelling—one on the way there and one on the way back but although land was tantalisingly close the crew was confined to the ship. The team deployed more than 100 Argo floats while they were away—adding these free-drifting scientific instruments to an international science network of more than 3800 floats across the world’s oceans to measure the role the oceans play in our climate and weather systems.
“When you’re on board you just concentrate on what needs to be done day by day.”
Scientists say the data collected by the Argo project has revolutionised our knowledge of ocean dynamics.
However, this year Coronavirus delays have disrupted Argo voyages around the world making maintaining coverage an increasing challenge.NIWA has deployed more than 1100 Argo floats in the Pacific, Indian and Southern Ocean over 22 voyages since 2004, more than any other individual vessel.
It will be tomorrow or Wednesday before the crew will finally set foot on land again—and Mr Brosnan gets his well-earned beer.
As for Kaharoa, she sets sail again this week on a new scientific voyage up the west coast of the North Island.
